Meeting the mental health needs of our current veteran population is one of the primary challenges facing the Veteran's Health Administration (VHA). Particularly for veterans residing in rural areas, the lack of providers, high provider turnover, and the burden of traveling long distances to VHA facilities may contribute to difficulties accessing mental health care. Telemental Health (TMH) services help bridge the geographic gap between mental health providers and veterans who need mental health services. The VHA TMH Hub initiative has attempted to leverage changes in technology-facilitated care by developing a model in which a facility "hub" could expand mental health resources to remote "spoke" clinics and veterans' residences. This paper describes the implementation of the VA New York Harbor Health care System (VA NYH) TMH Hub, which was one of 6 programs funded by the VHA Office of Rural Health (ORH) in September 2016. We will describe the structure of the program, services provided, veterans served, and our efforts to integrate quality improvement, research, and clinical training into the operations of the program.

Diabetes and hypertension are socially patterned by individual race/ethnicity and by neighborhood economic context, but distributions among Asian subgroups are undercharacterized. We examined variation in prevalence for both conditions, comparing between US Asian subgroups, including within South Asian nationalities, and comparing within subgroups by neighborhood economic context. We obtained data on a non-probability sample of 633,664 patients ages 18-64 in New York City, NY, USA (2014-2017); 30,138 belonged to one of seven Asian subgroups (Asian Indian, Bangladeshi, Pakistani, Chinese, Korean, Japanese, and Filipino). We used electronic health records to classify disease status. We characterized census tract economic context using the Index of Concentration at the Extremes and estimated prevalence differences using multilevel models. Among Asian men, hypertension prevalence was highest for Filipinos. Among Asian women, hypertension prevalence was highest for Filipinas and Bangladeshis. Diabetes prevalence was highest among Pakistanis and Bangladeshis of both genders, exceeding all other Asian and non-Asian groups. There was consistent evidence of an economic gradient for both conditions, whereby persons residing in the most privileged neighborhood tertile had the lowest disease prevalence. The economic gradient was particularly strong for diabetes among Pakistanis, whose prevalence in the most deprived tertile exceeded that of the most privileged by 9 percentage points (95% CI 3, 14). Only Koreans departed from the trend, experiencing the highest diabetes prevalence in the most privileged tertile. US Asian subgroups largely demonstrate similar neighborhood economic gradients as other groups. Disaggregating Asian subgroups, including within South Asian nationalities, reveals important heterogeneity in prevalence.

RATIONALE & OBJECTIVE:Current dietary guidelines recommend that patients with chronic kidney disease (CKD) restrict individual nutrients, such as sodium, potassium, phosphorus, and protein. This approach can be difficult for patients to implement and ignores important nutrient interactions. Dietary patterns are an alternative method to intervene on diet. Our objective was to define the associations of 4 healthy dietary patterns with risk for CKD progression and all-cause mortality among people with CKD. STUDY DESIGN:Prospective cohort study. SETTING & PARTICIPANTS:and dietary data in the Chronic Renal Insufficiency Cohort (CRIC) Study. EXPOSURES:Healthy Eating Index-2015, Alternative Healthy Eating Index-2010, alternate Mediterranean diet (aMed), and Dietary Approaches to Stop Hypertension (DASH) diet scores were calculated from food frequency questionnaires. OUTCOMES:(1) CKD progression defined as≥50% estimated glomerular filtration rate decline, kidney transplantation, or dialysis and (2) all-cause mortality. ANALYTICAL APPROACH:Cox proportional hazards regression models adjusted for demographic, lifestyle, and clinical covariates to estimate hazard ratios (HRs) and 95% CIs. RESULTS:There were 855 cases of CKD progression and 773 deaths during a maximum of 14 years. Compared with participants with the lowest adherence, the most highly adherent tertile of Alternative Healthy Eating Index-2010, aMed, and DASH had lower adjusted risk for CKD progression, with the strongest results for aMed (HR, 0.75; 95% CI, 0.62-0.90). Compared with participants with the lowest adherence, the highest adherence tertiles for all scores had lower adjusted risk for all-cause mortality for each index (24%-31% lower risk). LIMITATIONS:Self-reported dietary intake. CONCLUSIONS:Greater adherence to several healthy dietary patterns is associated with lower risk for CKD progression and all-cause mortality among people with CKD. Guidance to adopt healthy dietary patterns can be considered as a strategy for managing CKD.

OBJECTIVE:Altered hormonal regulation, including cortisol, is a proposed mechanism linking adiposity to obesity-related disorders. We examined the association of anthropometric, adipokine, and body fat distribution measures of adiposity with morning serum cortisol in an African American (AA) cohort. METHODS:We investigated the cross-sectional associations of adiposity measures (BMI, waist circumference, leptin, adiponectin, leptin:adiponectin ratio, subcutaneous and visceral adipose tissue) and liver attenuation with cortisol in the Jackson Heart Study. Linear regression models were used to analyze the association between exposures and cortisol. Models were adjusted for multiple covariates. RESULTS:Among 4,211 participants, a 1-SD higher BMI and waist circumference were associated with a 3.92% and 3.05% lower cortisol, respectively. A 1-SD higher leptin and leptin:adiponectin ratio were associated with a 6.48% and 4.97% lower morning serum cortisol, respectively. A 1-SD higher subcutaneous adipose tissue was associated with a 4.97% lower cortisol (all P < 0.001). There were no associations of liver attenuation or visceral adipose tissue with cortisol. CONCLUSIONS:Several measures of adiposity are associated with lower morning serum cortisol among AAs, with leptin having the greatest magnitude. Future studies examining the role of morning serum cortisol in the pathway from adiposity to cardiometabolic disease in AAs are warranted.

OBJECTIVE:To assess the Uniformed Services Constipation Action Plan (USCAP) as an evidence-based, personalized, clinical action tool with pictograms to aid clinicians and families in the management of functional constipation. STUDY DESIGN/METHODS:The USCAP facilitates the management functional constipation by using a health literacy-informed approach to provide instructions for pharmacotherapies and lifestyle modifications. This study included part 1 (pictogram validation) and part 2 (assessment). For part 1, pictogram transparency, translucency, and recall were assessed by parent survey (transparency ≥85%, mean translucency score ≥5, recall ≥85% required for validation). For part 2, the USCAP was assessed by parents, clinical librarians, and clinicians. Parental perceptions (n = 65) were assessed using the Consumer Information Rating Form (17 questions) to gauge comprehensibility, design quality and usefulness. Readability was assessed by 5 formulas and a Readability Composite Score was calculated. Clinical librarians (n = 3) used the Patient Education Materials Assessment Tool to measure understandability (19 questions) and actionability (7 questions) (>80% rating was acceptable). Suitability was assessed by clinicians (n = 34) using Doak's Suitability Assessment of Materials (superior ≥70% rating). RESULTS:All 12 pictograms demonstrated appropriate transparency, translucency, and recall. Parental perceptions reflected appropriate comprehensibility, design quality, and usefulness. The Readability Composite Score was consistent with a fifth-grade level. Clinical librarians reported acceptable understandability and actionability. Clinicians reported superior suitability. CONCLUSIONS:The USCAP met all criteria for clinical implementation and future study of USCAP implementation for treating children with chronic functional constipation.

SCOPE:Serum metabolomic markers of the Dietary Approaches to Stop Hypertension (DASH) diet are previously reported. In an independent study, the similarity of urine metabolomic markers are investigated. METHODS AND RESULTS:In the DASH-Sodium trial, participants are randomly assigned to the DASH diet or control diet, and received three sodium interventions (high, intermediate, low) within each randomized diet group in random order for 30 days each. Urine samples are collected at the end of each intervention period and analyzed for 938 metabolites. Two comparisons are conducted: 1) DASH-high sodium (n = 199) versus control-high sodium (n = 193), and 2) DASH-low sodium (n = 196) versus control-high sodium. Significant metabolites identified using multivariable linear regression are compared and the top 10 influential metabolites identified using partial least-squares discriminant analysis to the results from the DASH trial. Nine out of 10 predictive metabolites of the DASH-high sodium and DASH-low sodium diets are identical. Most candidate biomarkers from the DASH trial replicated. N-methylproline, chiro-inositol, stachydrine, and theobromine replicated as influential metabolites of DASH diets. CONCLUSIONS:Candidate biomarkers of the DASH diet identified in serum replicated in urine. Replicated influential metabolites are likely to be objective biomarkers of the DASH diet.

BACKGROUND:Vitamin D supplementation may prevent falls in older persons, but evidence is inconsistent, possibly because of dosage differences. OBJECTIVE:supplements on falls. DESIGN:2-stage Bayesian, response-adaptive, randomized trial. (ClinicalTrials.gov: NCT02166333). SETTING:2 community-based research units. PARTICIPANTS:688 participants, aged 70 years and older, with elevated fall risk and a serum 25-hydroxyvitamin D [25-(OH)D] level of 25 to 72.5 nmol/L. INTERVENTION:doses, and the best noncontrol dose for preventing falls was determined. After dose finding, participants previously assigned to receive noncontrol doses received the best dose, and new enrollees were randomly assigned to receive 200 IU/d or the best dose. MEASUREMENTS:Time to first fall or death over 2 years (primary outcome). RESULTS: = 0.54). Analysis of falls with adverse outcomes suggested greater risk in the experience-with-best-dose group versus the 200-IU/d group (serious fall: HR, 1.87 [CI, 1.03 to 3.41]; fall with hospitalization: HR, 2.48 [CI, 1.13 to 5.46]). LIMITATIONS:per day, not a placebo. Dose finding ended before the prespecified thresholds for dose suspension and dose selection were reached. CONCLUSION:doses of 1000 IU/d or higher.

CONTEXT/BACKGROUND:Germline testing (GT) is increasingly impacting prostate cancer (PCa) management and screening, with direct effects in urology, medical oncology, and radiation oncology. The majority of testing indications and recommendations center on men with metastatic disease, although guidelines now encompass newly diagnosed, early-stage PCa and entail assessment of personal history, pathologic features, and family history to determine eligibility for testing. OBJECTIVE:To describe current guidelines on GT for men with PCa and the impact on management. An additional objective was to review the literature on current uptake of GT across practice settings. EVIDENCE ACQUISITION/METHODS:A nonsystematic review was performed of current guidelines on GT in PCa from professional societies and consensus conferences, detailing supporting evidence for these recommendations. This was supplemented by a literature review of uptake of GT and precision medicine in practice. EVIDENCE SYNTHESIS/RESULTS:Multiple guidelines and consensus panels recommend GT for men with metastatic PCa. Guidelines endorse BRCA2 testing in metastatic PCa because of strong evidence for PCa risk, aggressiveness, and PARP inhibitor candidacy. Testing of additional DNA repair genes in metastatic disease is also endorsed across guidelines. Immunotherapy with pembrolizumab is an option in some guidelines for men with DNA mismatch repair deficiency. In localized disease, GT is recommended on the basis of histologic features and family history; criteria vary between guidelines. GT for localized disease informs hereditary cancer risk and will probably impact future PCa management. Practice gaps exist regarding utilization of GT. CONCLUSIONS:Germline evaluation is increasingly important in the management of men with metastatic PCa and may also affect the prognosis for men with localized disease. The presence of germline mutations has important hereditary cancer implications for men and their families. Uptake of germline evaluation may be underutilized in some practice settings, so strategies for optimization are required. PATIENT SUMMARY/UNASSIGNED:Patients with prostate cancer should talk to their doctor about the pros and cons of genetic testing, with attention to family history and cancer features. Genetic testing can have important implications for treatment, cancer screening, and family cancer risk.
